[The Fiction]

I think I really need help and some advice as to how should I deal with some stuff in my life.
I had used to have very bad anxiety, panic attacks and derealization, but I learnt how to cope with it and I really got so much better to the point I thought it's all totally behind me. But lately I've been experiencing some anxiety again, it's not as bad as it used to, mainly probably because I learnt how to accept it and to cope with it far better. The issue is, I still feel like there's something wrong, something doesn't fit, something bothers me... But it's usually not related to anything concrete that would be happening in my life. It's just a feeling in the back of my mind and no matter what I do, it's there. I can't really relax and I fear falling back into derealization again and that scares me even more than anything else.
The big issue is that everything seems very dull to me... my feelings, my environment, people...everything feels like it lacks something essential, but I can't point out what that is. Everything seems far from me, like I am outside of my own life. So things don't really make me happy, or anything.
I begun to have strange bodily sensations, I feel pains that come from nowhere and have no real explenation. I usually get so scared because of these pains that I make them even worse, I get super anxious and start to panic that I am dying over a minor ache.
I really don't know how to cope with that...any help? Adive please? Is this just a regular anxiety?

Depression and anxiety often go together. The dull feelings are related to depression rather than anxiety. Keep working on both.

Can I ask how often do you get these fears? Depression actually might be the primary issue here.
